I believe we will have Xen hypervisor and Linux dom0 packages, but they
will not be supported to the degree that ordinary kernel packages are.
The kernel team does not intend to carry Xen patches after squeeze, so
if dom0 support is not merged upstream then it will be gone in squeeze+1.

It does require virtualisation extensions, but most x86 processors sold in
the last few years have them.
